parentmerge: use return value of resolve_ref() to determine if HEAD is invalid (diff)

merge: remove global variable head[]
Also kill head_invalid in favor of "head_commit == NULL". Local variable "head" in cmd_merge() is renamed to "head_sha1" to make sure I don't miss any access because this variable should not be used after head_commit is set (use head_commit->object.sha1 instead).
